Lighting is a fundamental element in environmental design. What lights us depends on the application of lights: it needs to be subtle, powerful, and eye-catching. It influences our emotions in ways we cant even imagine. Light is used to create atmosphere, amplify architecture, create drama and provide art. It is a dramatic influence in both our outer and inner worlds. The care of the environment, the environment and cultural interpretation of our environment are fundamental to evolving the level of competency in our craft. It may be as much as natural in our space environment and culture as it is about technology. Lighting can create a brilliant, dappled effect with color, or a muted atmosphere with a cold, no-nonsense hue. With its potential to display depth of knowledge, dramatic design, artful positioning, and atmospheric play, lighting can become an exquisite medium of transformation, changing our physical and emotional space in ways we never dreamt possible. Lighting can also reduce power costs, increase safety, improve productivity and provide comfort. The use of good lighting techniques include choosing high energy-efficient lamp technologies, the specification of fixtures that direct light where it is needed, and the use of sensors that regulate lighting use by detecting when areas are unoccupied and automatically turning off unnecessary lighting. Lighting has come a long way in recent years, with advances in digital lighting technology and LED lighting becoming the new standard. The efficient use of LEDs, combined with smart control systems, gives building designers the ability to create lighting systems that are both beautiful and efficient—providing stunning visual effects while dramatically reducing energy costs. In summary, lighting is an essential element of design. With the right lighting, you can transfigure an area into the most romantic corner, the most modern space, or the warmest and most calming atmosphere. Lighting should be used with utmost thought and respect to create an effervescent space that is wholesome, dynamic, and invigorating.
